Welcome to LISTER

Short description:

These chiller models offer precise control of water temperature, an extremely compact structure and easy to use application. With the available models cooling capacity requirements from 3 to 760 kW can be met.

Each model ensures safe and reliable operation under all conditions.

Whether the water flows at 30 ° C or 5 ° C, if the outside temperature is 45 ° C or -10 ° C, the chiller always can work continuously and efficiently, thanks to modern technical solutions and the availability of numerous accessories. The modern technical implementations of chillers not only ensure flexibility of use, but also reliability, efficiency, energy saving, low weight and reduced dimensions, thus providing the ideal solution for all users.
